NEORINOPIS SEPULTA. 29 



The venation appears to be nearly similar to that of Anchiphlebia. It is 

 doubtful, however, whether the drawing of the veins has been sufficiently attended 

 to, to offer any reliable characters. 



In this paper he quotes Boisduval's locality "Aix en Provence," but when he 

 next refers to this insect 1 he gives it as from "Aix-la-Chapelle, "White sandstone," 

 a mistake, however, corrected subsequently. In this latter paper he remarks: 



I have discussed the position of this species in my catalogue of Satyridre, 

 pp. 189, 190; showing that its nearest ally is Neorina Lowii, a common Bornean 

 species, but that it also has a slightly more distant relationship to AntirrTiaea Phi- 

 loctetes and Anchiphlebia Archcea, two common tropical American forms; the 

 amount of affinity, as regards the first two of these species, may be seen on my 

 plate, figs. 4 and 5; the resemblance to Anchiphlebia is less striking, and the 

 affinity more doubtful ; it has nothing to do with Cyllo. 



That Butler should have so nearly pointed out the exact affinities of this 

 insect from the simple study of Boisduval's plate, is unquestionably due to his 

 extended familiarity with butterflies, and especially with the forms of this sub- 

 family; but it also shows the essential harmony between the markings of the 

 under and upper surface of the wings of butterflies, notwithstanding their fre- 

 quent great dissimilarity; for Butler compares this fossil with the recent forms on 

 the assumption that the under surface of the wings is seen in Boisduval's plate. 



The actual condition of the fossil, for an opportunity of examining which I 

 am indebted to the courtesy of Count Saporta, is this (see PI. I, fig. 13) : The 

 thorax, hind legs and both pair of wings of the left side are preserved, almost 

 completely; all the rest is lost. The thorax is viewed from above and somewhat 

 on the left side; the hind coxje seem to be almost torn away from their immediate 

 connection with the trunk. The two hind legs are stretched out bent at the 

 femoro-tibial articulation ; the left leg lies above both the wings and is apparently 

 attached throughout, although its base is covered a little by the crushed body; 

 the right leg lies below both the wings and is apparently partially detached, 

 though but slightly, from the coxa?; the tibio-tarsal articulation can be distin- 

 guished (PI. I, fig. 11) but not the tarsal joints. The wings are bent over
